11 multiple - choice 1 point

use the table above. if enzyme c is functioning at 25°c and ph of 7, under which condition would the rate of enzyme action probably increase the most?
the temperature is increased to 44°c and the ph is kept the same.
the temperature is increased to 30°c and ph is increased to 8.
the temperature is kept the same and the ph is decreased to 6.
clear my selection

enzyme	effective temperature range (°c)	optimum ph
b	30 - 40	3.5
c	20 - 38	9
d	20 - 27	7

Explanation:

Step1: Identify Enzyme C's optimal conditions

Enzyme C has an effective temperature range of 20 - 38°C and an optimal pH of 8.

Step2: Analyze each option

Option 1:

Increasing temperature to 44°C (outside effective range) while keeping pH same (7). Enzyme may denature, rate won't increase.

Option 2:

Increasing temperature to 30°C (within effective range) and pH to 8 (optimal pH). This will likely increase enzyme - action rate.

Option 3:

Keeping temperature same (25°C, within range) but decreasing pH to 6 (away from optimal). Rate may decrease.

Answer:

The temperature is increased to 30°C and pH is increased to 8.
